Title (EN) MOTION PICTURE FILM HAVING DIGITALLY CODED SOUNDTRACK AND METHOD FOR PRODUCTION THEREOF
(FR) FILM POUR PROJECTION ANIMEE POSSEDANT UNE BANDE SONORE CODEE DE MANIERE DIGITALE ET PROCEDE POUR LA PRODUCTION DE CELLE-CI
Abstract: front page image
(EN)This invention involves the production of sound tracks for motion picture film. Prior motion picture film sound tracks could not overlap the photographic image and were placed on the edge of the film, nor were they digitally coded to produce high fidelity. The motion picture film of the invention has a plurality of digitally coded sound track images which overlay at least a portion of the visible image (13, 14) area of the film and are colorless and transparent to visible light, but fluoresce when exposed to ultraviolet light. An electrostatic imaging process using a fluorescent toner which may be a polymer having covalently bonded 3-phenyl-7(amido or imido)-coumarin, certain substituted stilbenes or N-alkyl-4-aminophthalimides is used to form the sound track image.
(FR)Cette realisation concerne la production de bandes sonores pour des films de projection animee. Les bandes sonores des films de projection animee anterieurs ne pouvaient pas empieter sur l'image photographique et etaient placees sur le bord du film, et elles n'etaient pas codees de maniere digitale pour obtenir une haute fidelite. Le film pour projection animee decrit dans la presente realisation possede une pluralite d'images de bandes sonores codees de maniere digitale qui empietent sur au moins une partie de la surface d'images (13, 14) visibles du film et sont incolores et transparentes a la lumiere visible, mais fluorescentes lorsqu'elles sont exposees a la lumiere ultraviolette. Un procede de mise a l'image electrostatique utilisant un toner fluorescent qui peut etre un polymere lie de maniere covalente a un 3-phenyle7 (amido ou imidol-coumarine, certains stylbenes substitues ou N-alcoyle4-aminophtalimides est utilise pour former l'image de la colonne sonore.
